COA of Formula: C7H6BrNO2. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Methyl 6-bromonicotinate, is researched, Molecular C7H6BrNO2, CAS is 26218-78-0, about An Iridium(III)-Caged Complex with Low Oxygen Quenching. Author is Ruggi, Albert; Berenguel Alonso, Miguel; Reinhoudt, David N.; Velders, Aldrik H..
The synthesis, characterization and photophys. characteristics of the first iridium(III) complex with a caged ligand structure is reported. Thus, treating tripodal ligand (I) with 1 equiv of IrCl3·H2O and 3 equiv of CF3CO2Ag in refluxing ethylene glycol yielded, upon addition of LiOH and esterification with excess trimethylsilyldiazomethane, the iridium(III) hemicaged Me ester derivative II in 20% yield. Subsequently, II was hydrolyzed with LiOH and then subjected to DCC/HOBt (DCC = N,N’-dicyclohexylcarbodiimide, HOBt = hydroxybenzotriazole) coupling with tris(2-aminoethyl)amine, yielding the iridium(III) cage complex III in 22% yield. Iridium cage complex III shows an 80% decrease of oxygen quenching with respect to the archetypical Ir(ppy)3 (ppy = 2-phenylpyridyl), based on the Stern-Volmer plots of the three iridium complexes.
The article 《An Iridium(III)-Caged Complex with Low Oxygen Quenching》 also mentions many details about this compound(26218-78-0)COA of Formula: C7H6BrNO2, you can pay attention to it, because details determine success or failure
